Fox Business: Countries' defiance of EU ban on gas pipeline highlights Russia's energy clout in Europe

A clutch of countries is breaking ranks with the EU's efforts to put economic and diplomatic pressure on Russia over Ukraine and building a pipeline meant to carry huge amounts of Russian gas to their doorstep.

But their defiance of a European Union stop work order is more significant than just another missed chance for Europe to call out the Kremlin. Russian natural gas already accounts for around a third of the EU's needs. The South Stream pipeline could increase Russian supplies to Europe by another 25 percent, potentially boosting Moscow's leverage long after the Ukraine crisis fades.

Adding to the skein of Russian pipelines already ending in Europe, South Stream would go through Bulgaria, Serbia, Hungary, Slovenia, Austria and Italy in one leg and Croatia, Macedonia, Greece and Turkey in a second. The European Commission, the EU executive, has ordered a construction moratorium over concerns with Russia's dual role as pipeline owner and gas supplier. It has also delayed some political talks on the pipeline amid the crisis in Ukraine.
